Norway pollock
''Theragra finnmarchica'' or Norway pollock is a rare fish of family Gadidae (codfish) only known from the Barents Sea. Until recently, its known range would have made it an endemic species to Norway, but one specimen was captured from Russian waters in 2004. Moreover, current evidence suggests that ''T. finnmarchica'' is the same species as Alaska pollock (''Theragra chalcogramma'' or ''Gadus chalcogrammus''). The range of ''T. finnmarchica'' is fully separate from Alaska pollock, and the history of ''T. finnmarchica'' in the Barents Sea remains a mystery.
==Description==
''Theragra finnmarchica'' was described as a new species to science by Norwegian zoologist Einar Koefoed in 1956, based on two specimens landed in Berlevåg, northern Norway, in 1932 (hence the Norwegian name, "Berlevågfisk"). Based on morphological differences, Koefoed considered ''T. finnmarchica'' a new species related to but separate from ''T. chalcogramma''.
